ABSTRACT:
An apparatus and process for manufacturing multiple thin walled hollow shells for parts such as automobile door panels, arm rests, and instrument panels from thermoplastic plastisol includes a pair of plastisol charge boxes each forming a separate compartment and members for joining the charge boxes with an open ended mold. The mold has a divider rib thereon that is inaccessible by straight vertical engagement of a seal assembly on the divider. An indexable divider wall is operatively connected between the charge boxes so that the divider wall can be selectively extended and retracted at an angle with respect to the vertical and against the mold at the divider rib thereon for allowing separation of the casting surfaces having different colors fixed thereon and the subsequent fusing of the casting surfaces to one another at the divider.
